Do you have to use integers? A DCELL (double-precision floating point)
map can store integers up to 2^53 (~10^16) exactly.
No - I don'y have to use integers - DCELL would be fine as well. but how
can I change the format? The raster is created from an imported shape file.
In a second step I want to use r.reclass() to create the second raster
which holds the large cell values. Can I specify in r.reclass() that the
cell values should be stored as DCELL?
No, at present, reclass maps are restricted to integers.
That's a pitty - it would be nice to have an option to specify that the
reclassified raster map holds floats instead.
But, if you're creating a reclass map, you can use r.reclass to set
the category labels when the map is created.
Thanks - how could I have missed that? I read the manual page several
times...
